I think practically you'll need to get as much camber as you can.
With camber bolts you'll only get -2º or so, which will not be enough.
With some questionable trickery (two camber bolts) you can get more, but still not enough.

I have -3.2º by using coilovers with camber plates that are maxed out.
With this much camber the stock front end links were hitting the chassis when entering driveways.
And yet the outside shoulders of my front tires still show more wear than rears (-2.5º).
